Indeed, many old people scrimp and save. Just because of their frugality, but now people's living standards have improved. When they get old, people stop looking for food and drink, but look for a healthy and long life. How can they live such a good life? Of course, they live and earn one more year, so health is the most precious wealth in their consciousness.
They are eager to pursue something for health. Just look at the news of the mobile phone circle of friends. Most of the overwhelming health news is forwarded by the elderly, and they can't wait to buy health care. However, those health care products may not be real drugs, and they have no health care function. They are just instilling an idea that everything can be changed as long as they are used.
To put it bluntly, they are actually selling their dreams, and the dream of the elderly is health and longevity, so they will associate these products with health and longevity and then sell them all to the elderly. Some people can refuse extravagance and waste, but if they invest in their own health, no one will feel wasted. One of their ideas is, what's the use of having money when you are old? You can't take it away. If you invest this money in health, will you live longer than anything else?
